/-//5 ATTORNEY 1 STRONG BOX AND FIXED ANCHORAGE AND MEANS FOR INTERCONNECTING AND LOCKING TI-IEM TOGETHER BACKGROUND This invention relates to a novel locking means between an anchorage and a strong box for securing the latter against theft and/or unauthorized access thereto.
The broad concept of securing a strong box to a fixed base is not new. There are numerous patents in the prior art showing in general the arrangement of a strong box, carrying case and the like secured to a base in the form of a fixture to realty, a vehicle or any form of conveyance during transit. Among such prior disclosures, British Pat. No. 933,245 which issued to Jack Maurice Hall Aug. 8, 1963, shows the general arrangement as having what he calls locking spigots projecting from the strong box and insertable into openings formed in a fixture attached to a floor. These spigots have spring latches operatively related with a lock mechanism on the strong box for releasing such latched spigots from latched engagement with the base or fixture. The spigots project from the bottom of the strong box and serve as foot members or legs and due to such projection are easily damaged by sidewise blows. In other disclosures it is the latch and locking mechanisms between the strong box and the fixed base which constitutes the invention thereof. The present invention has its embodiment in a novel construction of the base i and locking mechanism as well as the strong box for providing a simple, economical and effective means for interrelating the general components with each other.
STATEMENT OF INVENTION It is an object of the present invention to provide a fixed base constructed for interlocking relation with a strong box and provided with a latch bolt projecting upwardly into the box for locking engagement with a lock operated latching lever internally of the box.
It is another object to provide such a fixed base for a strong box having its lid lowermost for confinement within the base to obstruct access to the box when it is latched to the fixed base.
It is another object to provide a separate lid and closure means for the open bottom of a strong box and adapted for confinement within the fixed base during securing of the strong box thereto.
It is yet another object to provide a fixed base adapted for nesting the lidded bottom of a unitary bodied carrying case with an integral keeper bolt disposed forlatching engagement with a spring loaded latch lever within such case for automatically locking the latter to the fixed base.
It is a still further object of this invention to provide a hinge interconnection between one end wall of the case and the fixed base and means adjacent the opposite end of said case and said base for automatically locking them together as said case is swinging into parallel, nested relation with the fixed base.
These and other objects and advantages of the present invention will be made more apparent in the following description in the light of the accompanying two sheets of drawings in which:
FIG. 1 is a perspective view of a strong box and base embodying the present invention;
FIG. 2 is an enlarged perspective view of the base only of FIG. 1 and at a larger scale;

GENERAL DESCRIPTION Referring to FIGS. 1, 2 and 3 the present invention has its embodiment in certain novel improvements in the structure of a strong box 10 consisting of a carrying case 11 adapted to be lockingly secured to a base 12 affixed to a floor or surface of a building, edifice, vehicle and the like as a permanent fixture thereof.
DETAILED DESCRIPTION The carrying case 11 has the usual top 13, side walls 14 and 15 as well as end walls 16 and 17 to provide an internal receptacle for valuable papers, documents and the like, access to which may only be had through an open bottom 18 in accordance with the present invention. The open bottom 18 of the case 11 is provided with a closure number in the form of a lid 19 adapted to be secured to the case 1 1 in a manner to afford portability of the latter when detached from the base 12. For this reason the top 13 is provided with a handle 20.
The open bottom 18 of the case 11 is provided with a shoulder portion 21--21 along its sides 14 and I5 and internally of the open edge of the bottom a distance comparable to the thickness of the lid 19. This provides a seat 22 for the lid 19 to thus support the latter flush with the open bottom 18. The end wall 17 of the case 11 has a projection 23 extending interiorly I therefrom slightly less than the thickness of the lid 19 to receive a lip 24 projecting from one end of the lid to secure that end of the lid in place with the lid resting upon the seat 22 provided by the shoulder portions 2121 (FIGS. 9 and 10). A latch or locking means 25 is provided between that end of the lid 19 opposite the lip 24 for securing the lid in place on the seat 22.
The base 12 as shown in FIG. 2 comprises a pan 26 of heavy gauge steel providedwith an upwardly extend ing flange-like edge 27 conforming to the shape and size of the case 11 to receive the latter, bottom side down for nested relation therewith. This pan-like base 12 is adapted to be anchored to the fioor of a building, vehicle and the like by means of anchor bolts 28 (FIG. 4) extending through the pan 26 in a manner well known in the art. One edge 27' of the pan 26 is provided with an inturned enlargement 29 spaced slightly from the pan to receive an outwardly extending lip or flange 30 (FIG. 4) on the bottom edge of the end wall 17 of the case 11. The opposite end of the pan 26 is provided with a keeper bolt 31 welded to or therewise formed integrally with the steel pan.'This keeper bolt 31 is disposed in spaced relation to the upstanding flange 27 opposite the edge 27' for latching engagement with latch mechanism 32 within the case 11.
Referring now to FIGS. 3, 4, and 6 the latch mechanism 32 is confined within a chamber 33 provided between the end wall 16 and a partition 34 parallel thereto and welded to the side walls 14 and of the case 1 1 transversely thereof. As best seen in FIG. 7 the chamber 33 is closed at its bottom by a bottom plate 35 which is permanently secured to the end wall 16, partition 34 and side walls 14 and 15 by welding. The bottom plate 35 has a recess 36 formed adjacent the side wall 16 and the upper surface of plate 35 is provided with a slot 37 through which the keeper bolt 31 may pass when the case 11 is lodged upon the base 12.
7 As shown in FIGS. 5 and 7 the keeper bolt 31 is offset slightly of center and has a notch 38 formed therein facing center of the pan 26 to engage a notch 39 formed in one edge 48 of a latch lever 40. The latch lever 40 is pivotally mounted as at 41 on one wall 16 of the chamber 33 at approximate center of the case 1 1 and is urged by a spring 42 toward the keeper bolt 31. The spring 42 is tensioned between the latch lever 40 and an anchor pin 43 mounted on the wall 16 of the case 11 within the chamber 33.
The latch lever 40 is limited in movement toward the keeper bolt 31 by a lock 44 having its chassis 45 mounted within the chamber 33 on one wall 16 thereof. The lower notched end of the latch lever 40 extends into the slot 37 formed in the hollow plate 35 in a manner such'as to cammingly engage the rounded upper end 46-of the keeper bolt 31 when the chambered end 33 of the case 11 is lowered into nested relations with the pan 26 of the fixed base 12. By this arrangement the 48'of the latch lever 40 above the notch 39 formed therein. Upon operation of the lock 44 by the key K the slide bolt 47 urges the latch lever 40 away from the chassis 45 against the action of the spring 42. This rocks the latch lever 40 away from the keeper bolt 31 (dotted lines FIG. 7) to disengage the notched connection therewith. Thus the case 11 can now be lifted chambered end first out of the pan 26 to a level wherein the flange on the opposite end wall 17 of the case can be slidably withdrawn from the intumed enlargement 29 on the flange 27' of the pan 26.
In conjunction with the foregoing it will be noted that the manner of interconnecting that edge 27' of the base 12 with the case 11 may be in the form of pins 30' and holes 29' on opposite members as shown in FIGS. 10 and 1'1. The general arrangement remains the same in that end wall 17 of the case 11 opposite the locking means is first adapted to slide angularly into interlocking relation with the edge 27' of the pan 26. Thereafter the slanted bottom of the case is lowered hinge-like into parallel, nested relation with the fixed base pan.
Thus, in either event the keeper bolt 31 will be received up through the slot 37 in the bottom plate of the 5 lock containing chamberas the case 11 is brought into nested relation with the pan 26. As the case 11 thus lowered, the lower end of the latch lever cammingly engages the rounded top of the keeper bolt 31 for automatic latching engagement therewith.
From the foregoing it will be appreciated that the simplified construction as explained provides a security strong box which serves as a carrying case having an open bottom closable by a lid which seats into the recessed or shouldered open edges for locked engagement with the case itself during partability. More important, however, the present invention provides a simple, economical and effective lock and latching construction between the strong box and a base pan affixed to realty, a conveyance and the like in such a manner as to preclude removal short of complete destruction of the strong box when so nested and locked to the base.
Having thus described the lock and latching mechanism between a strong box and fixed anchorage in specific detail it will be appreciated that the same may be susceptible to modification, alteration andvariations without departing from the spirit or scope of the invention therein as set forth in the appended claims.
